Sony Alpha 7
The Sony Alpha 7 is a full-frame E-mount mirrorless camera. The A7 is very similar to its more expensive sibling (the A7R), except that it uses a 24 megapixel CMOS sensor with on-chip phase detection. The A7 twins are the smallest and lightest full-frame cameras on the market.
While the cameras can use any E-mount lens, there will be a crop factor involved (unless you don't mind vignetting). Sony is producing a new line of FE-series lenses that take advantage of the larger sensor.
The A7's use the new Sony Bionz X processor, which produces images with better detail, less noise, and reduced diffraction. Other features include a 3-inch, tilting LCD, XGA OLED electronic viewfinder, Multi-interface (hot) shoe, Wi-Fi with NFC, and 1080/60p video recording.

The Alpha 7 has broken new ground in the full-frame market, in terms of both size and price. Its compact size, broad feature set and very good Raw image quality make it a compelling option for those wanting a large sensor. Unfortunately, the JPEGs have many issues, performance and battery life could be better, and the controls would benefit from a re-think.
Good for: Those seeking a full-frame sensor in a small body, determined third-party and historic lens owners, video enthusiasts, and social media mavens
Not so good for: JPEG shooters, Auto ISO users, and photographers who want to quickly capture a moment
